The book really exists, although its title was misspelled in the title and first message of this thread, which made it difficult to find.

<rant>Dang it! Why can't people learn to be careful when they copy down an unfamiliar word? Don't they know that having even one letter wrong will screw up a search with a search engine? Even Google was no help this time. It asked 'Did you mean "Il Pes Caballo"?'

And of course the link is dead now, so that's no use, either.</rant>

The title, correctly spelled, is Il Pesceballo: Opera in One Act, Italian words by Francis James Child, English version by James Russell Lowell (Chicago: The Caxton Club, 1899).

An online facsimile can be seen at The Hathi Trust Digital Library.

I didn't see any musical notation in that copy, but I haven't read the whole thing.
